I've been acting for years and years, at prep school - school plays, that kind of thing. That was always very high on my agenda. I went to study English for two reasons. Principally because when I was in university, studying drama wasn't considered an option. You couldn't get a degree course for it. And so many plays and things that I was interested in landed themselves in a broader spectrum of literature.

On a personal note, myself, I find religion - I can understand it, I can understand why we have it, as a kind of force on the planet. And I also at the same time think it's ludicrous. My Latin education teaches me that religion comes from religio, which means, "to bind." To bind with rope. And that's all it means.

What would I like? Some very silly comedy where I don't have to think about anything, but it could be a lot of fun. And if it's not that, then I'll want to be involved in something where it's like, you're really dredged up to the neck in emotion, where it's as exciting as the premise of Battlestar.

I was convinced that I was going to be onstage for the rest of my life.

I went to Los Angeles, because I have a manager, and - I can't remember when, but we met in London maybe six months or a year beforehand, and he said, "Listen, if you really want to get a job out of L.A., you really need to come." And I was like, "Well, can't I send a tape or something?" And he was like, "No, no, you need to come."

Anybody who has political ambition has an Achilles heel.

I did worry about being in a science-fiction show. The bits that I was reading, I felt were funny, and I felt the man was childish, so I really did ask initially, "Is this for kids?" And the thing that came back immediately was like, "Hey, take a look at this whole thing again. This is definitely not for children. How can you think that?"
